APPARATUS FOR BURNING PETROLEUM.

- izin g liquid hydrocarbon, superheatin g steam,

and mixing the steam and the hydrocarbon vapor together in the presenceof an intense heat, so as to decompose the steam and form a burning gasthat mingles with the volatilized hydrocarbon and is burned in theatmosphere so as to produce an intense heat and flame that is adapted tothe generation of steam in boilers and for heating purposes generally.

In the drawings, Figure 1 is a plan view of our improved apparatus. Fig.2 is a vertical section of the same at the line 00 00. Fig. 3 is asection at the line y y. Fig. 4 is a vertical section of the end of thepetroleum-pipe and of the steam-pipe with which it is connected, in amodified form, and Fig. 5 is an inverted plan of the same.

WVe make use of a generator, E, supported by tubular legs L, said legshaving at their upper ends elbows that are screwed into openings at thesides of the generator E.

The mixer or generator E is in the form of a metal box, preferablyquadrangular and provided with a bottom, a, that may be removed andreplaced if injured by the action of the heat. Within this generatorEthere are partitions e, and the steam and hydrocarbon vapors are mixed,as hereinafter described, in the central portion of the generator, beingconfined by these partitions e, and the inflammable fluids descendbeneath these partitions e and rise up and escape by the legs. Petroleumor other hydrocarbon liquid is supplied into the generator E by the pipe0, and steam under pressure is caused to pass through the pipe N fromany suitable boiler, and to pass backward and forward through the coilsN of pipe, so that the steam becomes superheated by the flame that actson the outside of the coil N, and the superheated steam enters thegenerator E, and the pipe 11 and petroleum-pipe C terminate adjacent toeach other within the generator E, so that the superheated steam issuingfrom the pipe n comes into direct contact with the petroleum or otherhydrocarbon liquid issuing from the pipe 0, and it is preferable tomakethe issuing steam atomize or scatter the liquid hydrocarbon, so thatthe heat to which the materials are subjected within the generator E maycause the oxygen of the steam to combine with a portion of thehydrocarbon oo vapor and liberate the hydrogen of said steam and causeit to commingle with the olefiantgases and pass through the tubular legsL in a condition adapted to rapid and perfect combustion in theatmosphere.

The pipe C, through which the liquid hydrocarbon reaches the generatorE, is preferably incased with two tubes, 0 0 containing non-conductingmaterial such as asbestus or mineral wool or plaster-of-paris-so as toprevent the liquid being volatilized within the pipe 0. We prefer tomake use of an annular case surrounding the lower end of the pipe 0 and.having a circular range of perforations around 7 5 such pipe, so thatthe highly-superheated steam from the pipe n comes into direct contactwith the petroleum as it issues from the end of the pipe 0, as shown inthe detached section, Fig. 4, and inverted plan, Fig. 5.

In Figs. 1, 2, and 3 we have represented branch pipes n 'n n n with acock in each, by which the superheated steam is conveyed into thegenerator and issues by jet-nozzles contiguous to the end of the pipe 0,and by leading the pipe 02 at an inclination into the pipe O,near theend thereof, the steam acts as an ejector and atomizer upon the liquidhydrocarbon. In all instances the liquid hydrocarbon is instantlyvolatilized and com- 0 bines with the superheated steam, forming thehighly-inflammable mixture which is burned, as before set forth.

The lower ends of the legs L are connected to the horizontal sockets Land from these 5 extend out laterally thetubular frames L that areperforated on opposite faces and receive between them the slotted orperforated tubes P, and usually the legs L are connected by the slottedtube Q. There is a valve-seat in each of the sockets U between the placewhere the legs L connect to the same and the tubular frames L and thereare valves 1 upon a stem, '2", that terminates as a screw, 1 passingthrough a coupling or cap at the end of one of the sockets L By means ofthis screw 0' the stem and valves are moved to open and close the seatsand regulate the supply of burning gas passing from the tubular legs Lto the pipes P, or allowing the gas to be cut off from the same.

The pipes P P and Q may be partially rotated by a let er or wrench tobring the slot or line of perforation along the top of each tube into aproper position for directing the flame more or less upon the generatorE. It is preferable to make the bottom of this generator E with a doubleinclined plate, 8, so that the heat may act upon the generator to thebest advantage. The heat which is not required upon the generator orsuperheating-pipes passes off and is made use of in heating boilers orother articles. The double incline in the bottom 6 causes any liquidhydrocarbon to spread and become volatilized, and said bottom maybe.removed, if it is worn out, and another substituted.

The supply of petroleum or other liquid hydrocarbon to the pipe 0 andthe supply of steam to the pipe N are to be regulated by cocks of anysuitable character, so that the steam will be in the proper proportionto the petroleum for obtaining the best and most perfect combustion. Thecocks may be provided with index-hands to show the extent of openin Itis to be understood that the tubular frames L and pipes P P Q willusually be provided at the bot-tom of eachpair of tubular legs L, so asto pass off in opposite directions, as shown; but where the fire-chamberin a boiler is not sufficiently large the tubular frames L and pipes P PQ may be used with only one pair of legs L.

It is preferable to place the apparatus upon a brick-work foundationwithin the furnacespace of the boiler, as seen at A, and to provide oneor more openings through this foundation at A for the passage ofatmospheric air into the fire-chamber, which air, commingling with theheated gases that issue from the pipes P P and Q,will produce a veryperfect combustion and an intense flame, and such flame may pass throughthe tubes or flues of the boiler for heating the same. Usually the gasesissuing from the openings in the tubes Q will be sufficient for heatingthe generator, and the remaining flame and hot gases will act upon thesteam-boiler or other thing to be heated; and we provide a bonnet, U, inthe form of a truncated pyramid, of sheet metal or other suitablematerial, surrounding the generator and confining and directing theflame upon the generator, and the bridge-wall R, that rises as high asthe generator, causes the heat to rise and pass off, preferably abovethe generator, before acting upon the boiler or other article for whichit has been constructed.

When the apparatus is first started, the necessary heat may be obtainedby charcoal or other fuel beneath the generator, and to facilitate thisoperation a removable grate or pan for fuel may be introduced, as shownby dotted lines at S, Fig. 2, and a blast of air to the same may bedirected by a pipe into the space below this grate.

Plugs may be inserted in the bottom 6 of the generator for drawing offany residuum that may accumulate in the said generator.

We claim as our invention 1. The tubular frames L and the slotted orperforated pipes P, passing across from one tubular frame to the otherand capable of being partially rotated, in combination with the tubularlegs L, generator E, super-heating steam pipe and coil, and the pipe forsupplying liquid hydrocarbon, substantially as set forth.

2. The tubular legs L, tubular sockets L valve-seats, and valves, incombination with the tubular frames'L, slotted or perforated tubes P Pand Q, generator E, petroleum-supply pipes G, and pipe for supplyingsuperheated steam into such generator, substantially as specified.

The generator E, formed as a hollow box with partitions e and a doubleinclined bottom, 6, in combination with the pipes for supplying liquidhydrocarbon and superheated steam into such generator and comminglingthe same within the generator, pipes for conveying away the inflammablegases, and perforated pipes below the generator, from which the gasesissue and are burned beneath the generator and the superheating-pipes,substantially as'specified.

4. The generator E, having within it the partitions c, in combinationwith the tubular legs L, for supporting the generator, the perforatedpipes Q, for the issuing gas that is burned to heat the generator, andthe superheating steam-pipes N, passing across below the generator,substantially as specified.

5. The generator E, having a double i11- clined bottom, in combinationwith the oilsupply pipes and the pipe for superheated steam, bothdischarging downwardly, so that the combination of the steam andhydrocarbon vapors is promoted by contact with the heated interior ofthe generator, substantially as specified.
